Some challenge

Pokemon Emerald Plus Plus is my (mynameisPooky) first-ever ROM hack based on the Pokeemerald decompilation. I’m incredibly grateful to everyone who has contributed to both the decomp and the expansion, as I couldn’t have done this without that foundation. I began this ROM hack in August as a fun way to learn the ins and outs of the decomp, and what started as a small project quickly snowballed into something much bigger. Is it unique? Probably not. I’m aware that there are plenty of “Emerald but better/modern” hacks out there, but I honestly didn’t even know about them until I was deep into this project. My hope is that, even if this hack doesn’t stand out as particularly unique, it still offers an enjoyable “modded” Emerald experience. I hope you have fun playing it!

MISSION REPORT — POKEMON EMERALD PLUS PLUS

Explorer: DexHunter Ace (LVL. 100)
Region Base: Hoenn (Emerald Sector)
Build: v10.1 by mynameisPooky
Status: Expedition Complete — Dex at 98.7%. I'm still twitching about that last 1.3%.

INITIAL DEPLOYMENT — 00:00:00

Dropped into Littleroot like I've done a hundred times before, except this time the air felt different. The local flora and fauna have been radically expanded — we're talking every documented species through Generation VII roaming this region. SEVEN GENERATIONS in Hoenn. My Pokedex practically screamed when I booted it up. 809 slots staring at me. Empty. Hungry. Beautiful.

Within the first hour I knew this was going to consume me. I logged my first catch timestamp at 00:04:32. A Rowlet. In Hoenn. On Route 101. My hands were shaking.

REGIONAL PHENOMENA & LOCAL TECHNOLOGY

This region has adopted some seriously civilized infrastructure. Let me break down what matters to someone who lives and dies by the Pokedex:

  • HM Abolition Protocol: HMs have been converted into key items. No more sacrificing a party slot to a Surf/Fly mule. I almost cried. My team composition was mine from start to finish. Best QoL feature I've encountered in the Hoenn sector, period.
  • Multi-Register Key Items: Up to 4 key items registered simultaneously, ORAS-style. Fishing Rod, Bike, Repel toggle — all one button press away. Best QoL: Infinite Repel system. Well, not technically infinite, but the toggle system means I never accidentally walked through grass unprotected. My blood pressure thanks this region's engineers.
  • EXP Share (Full Party): Toggleable. I kept it ON for the main expedition because I was rotating a living dex assembly line of 30+ species at any given time. Grinding is optional. That word — optional — is music.
  • Bag Sorting & Expanded Capacity: Finally. FINALLY. When you're hoarding 400+ items for evolution stones, held items, and specialty balls, bag management is not a luxury. It's survival.
  • Following Pokemon: Every single species can follow you. Every. Single. One. I toggled it on immediately and never turned it off. Watching my Wailord try to squeeze through Mauville City was a religious experience.
  • Day/Night Cycle (RTC-Based): Critical for time-locked encounters. Certain species only appear at night, others at dawn. I adjusted my real-world sleep schedule accordingly. No regrets. Some regrets. My doctor has opinions.

THE DEX — THE ONLY THING THAT MATTERS

Let me get to the heart of why I'm here. The Pokedex situation.

All 809 species through Gen VII are catalogued as obtainable in this region. Trade evolutions? Let me tell you something that made me stand up from my chair and salute my screen: Link Cable item is available in Department Store. Huge W. No need for a second explorer, no need for external trade protocols, no link cable anomalies. You walk into the Lilycove Department Store, you buy the item, you evolve your Haunter into Gengar like a civilized human being.

Living Dex is possible without cheats. I confirmed this through 72 hours of fieldwork. Every evolution stone is obtainable. Every trade evolution has an in-region solution. Every version-exclusive from the original Emerald split? Present. Both fossil lines? Available. I went through my spreadsheet line by line. Green checkmarks across the board — with a few asterisks I'll address below.

MISSABLE EVENT WARNING! Some legendary encounters are gated behind story milestones and specific map triggers. I encountered one anomaly where entering Sky Pillar before completing the Sootopolis event chain locked me out of a secondary encounter sequence. Missable event warning! Save before entering the cave. Always. ALWAYS maintain a backup save before any legendary encounter zone. This is non-negotiable field protocol.

All legendaries and event-exclusive mythicals are catchable within the region. No external distributions, no Mystery Gift ghosts, no "you had to be there in 2006" nonsense. Mew, Deoxys, Jirachi, Celebi — they're HERE. Some require post-game access, some require milestone completion, but they're ALL documented as present. I caught Mew at hour 58. I may have screamed.

ROAMING ENTITIES — ROAMERS PLUS SYSTEM

The region utilizes something called RoamersPlus — multiple legendary species roaming simultaneously. This is both a blessing and a torment custom-built for my specific brain chemistry. At one point I had Raikou, Entei, Suicune, AND Latias all bouncing between routes. My tracking spreadsheet had four color-coded tabs open. I was cross-referencing route probabilities against time-of-day windows. 100% completion took me 85 hours. Honestly, 73 of those hours were chasing roamers and filling the last 40 dex slots. The other 12 were the actual story.

HOSTILE ENTITIES & THREAT ASSESSMENT

The region's trainers have been upgraded. Updated teams, improved AI, better held items, actual strategy. Gym Leaders don't just sit there anymore — they switch, they predict, they punish overleveling with scaled teams. The Dynamic Trainer Levels system means the region scales with your party. You can't just outlevel everything and coast.

Threat level: Moderate to High. Not Radical Red levels of punishment, but noticeably above vanilla Hoenn. I wiped twice to Winona because her team had coverage moves I wasn't expecting. Tate & Liza brought a full squad with Trick Room support. Juan had a Rain team that would've made competitive players nod approvingly. The Elite Four was a genuine gauntlet — I had to actually plan. With real strategy. Like an animal.

For context, this isn't a difficulty hack. It's a smarter version of the same region. Trainers don't have perfect IVs and optimized EVs like in the hardcore sectors — they just make better decisions and carry better coverage. Fair but firm.

POST-GAME ASSESSMENT

Post-game is massive. Battle Frontier included. The original Emerald Battle Frontier is intact and operational, which alone adds dozens of hours for facility completionists. On top of that, the legendary hunt across the region kept me busy for another 25+ hours post-credits. Multiple islands, caves, and dimensional rifts open up after the Champion is defeated, each housing legendary encounters with level-appropriate challenges.

The Shiny Charm is obtainable after completing the National Dex. I confirmed this. The moment that charm hit my bag, I immediately began shiny hunting protocols. The base shiny rate with charm applied feels consistent with expected Gen VII odds. I did not detect any DexNav chaining system specifically, so hunting relies primarily on the charm plus soft resets for static encounters. Random encounter shiny hunting is viable but patience-intensive — standard operating procedure.

ANOMALY LOG

I need to document some irregularities:

  • Following Pokemon Collision: Certain larger species clip through environmental geometry in tight indoor spaces. Cosmetic only — no gameplay impact. But watching Steelix phase through a Pokemon Center wall is... unsettling.
  • Roamer Tracking: The Pokedex does not always update roamer locations accurately after area transitions. I experienced a few instances where the map indicator showed Route 110 but the roamer had already migrated. Minor, but when you're on hour 4 of chasing Entei, every false positive is a small death.
  • Evolution Move Learning: Mid-battle evolution is a fantastic regional phenomenon, but I observed one instance where a newly evolved species did not prompt for move learning until the battle ended. Could not reproduce consistently — may be a one-off anomaly.
  • Text Overflow: Some ability descriptions in the summary screen extend beyond the text box for longer Gen VII ability names. Purely cosmetic.

None of these anomalies are expedition-breaking. This is a stable, completed region. I encountered zero crashes, zero softlocks, zero save corruption across 85 hours. That's clean.

FIELD ASSESSMENT SUMMARY

Here's what mynameisPooky built: a modernized Hoenn that respects the completionist's time. Every quality-of-life innovation points toward one goal — making it possible to catch them all without external tools, without trade partners, without event distributions locked behind expired servers. The region doesn't reinvent Hoenn's geography or narrative. The story is vanilla Emerald with smarter opponents. And honestly? That's fine. Because the real story was always the Pokedex.

Is it the most unique expedition I've undertaken? No. There are flashier regions, harder regions, regions with custom stories that made me feel things. But Emerald Plus Plus is the Hoenn expedition I've wanted for years — one where I can actually finish the dex without begging someone on a forum for a Gengar trade. The 98.7% on my counter is because I'm still hunting two roamers. They will not escape me. I have the spreadsheet open. I have Repels. I have time.

I'll sleep when the Dex says 100%.
